Partner with us to build a fitness app that doesn't just compete-it defines the future of the industry.
In an era where personal health data is both valuable and vulnerable, our commitment to robust security and regulatory compliance is absolute. We understand that for health and fitness apps, trust is paramount.
That's why we build security into the very fabric of our development process, ensuring that your application and your users' sensitive data are protected by the highest standards of data privacy and security. Our dedicated DevSecOps and Healthcare Interoperability Pods ensure that from day one, your app is not just innovative and user-friendly, but also a fortress of data integrity.
Here's a look at our compliance and security expertise:
We ensure strict adherence to HIPAA regulations by implementing robust encryption and secure data storage, safeguarding user data and mitigating compliance risks for you.
Our applications are built to respect user privacy and data protection rights under GDPR, with granular consent management for apps targeting a European user base.
Our development is governed by SOC 2 and ISO 27001 certifications, providing an enterprise-level security framework that ensures the highest levels of data security.
We integrate security measures throughout the development lifecycle, from initial design to deployment, and conduct rigorous penetration testing to address any vulnerabilities.
We implement end-to-end encryption for all data, both in transit and at rest, to ensure your users' sensitive information is consistently and comprehensively protected.
The cost can vary significantly based on complexity, features, and the platforms (iOS, Android, Web). A simple MVP might start around $25,000-$40,000, while a complex, AI-powered app with extensive features could range from $80,000 to $250,000+. We provide a detailed, transparent quote after our initial discovery phase.
Similar to cost, the timeline depends on the scope. An MVP can typically be designed and launched in 4-6 months. A more feature-rich application can take 6-9 months or longer. Our agile process is designed to get a core version of your product to market as quickly as possible.
Security is at the core of our process. We are SOC 2 and ISO 27001 certified. We start with a strict NDA, implement secure coding practices, conduct regular vulnerability testing, and ensure all data is encrypted at rest and in transit.
